At Meta Mechanics, we recently completed a brake oil change on an Audi TT MK2 in Dubai. Brake oil, also known as brake fluid, is an essential part of your vehicle’s braking system. It transfers force from the brake pedal to the braking components (such as the brake calipers) and ensures that the system functions efficiently. Over time, brake fluid can degrade due to moisture absorption, contamination, or heat, leading to reduced braking performance and safety concerns. Here’s a look at the issues we identified and the solutions we provided during the service.
Issues Identified and Solutions Provided:
- Brake Fluid Contamination
- Problem: Upon inspection, we found that the brake fluid was contaminated with moisture and debris. Moisture in brake fluid can cause a decrease in boiling point, which can lead to brake fade (loss of braking power) under heavy braking.
- Solution: We drained the old, contaminated brake fluid and replaced it with fresh, high-quality brake fluid. We also performed a thorough flushing of the brake lines to ensure that all contaminants were removed from the system, restoring the fluid’s integrity and improving braking performance.
- Old, Degraded Brake Fluid
- Problem: The brake fluid was aged and had lost its ability to perform effectively. Old brake fluid can lead to poor braking response, longer stopping distances, and a spongy brake pedal feel.
- Solution: After draining the old brake fluid, we refilled the system with premium brake fluid that meets or exceeds Audi’s specifications. This ensured that the braking system functions smoothly and reliably.
- Low Brake Fluid Levels
- Problem: The Audi TT MK2 was experiencing low brake fluid levels, which can result from leaks or natural fluid loss over time. Low fluid levels can cause air to enter the brake lines, leading to a spongy brake pedal and reduced braking efficiency.
- Solution: We topped up the brake fluid to the manufacturer-recommended level, checking for any signs of leaks in the brake system. The fluid was replenished to ensure that the brake system operates at full capacity.
- Brake Fluid Overheating
- Problem: Overheating of the brake fluid can cause a drop in its effectiveness, which is particularly dangerous during high-performance driving or when the vehicle is frequently subjected to heavy braking.
- Solution: After flushing the system, we used high-performance brake fluid that is designed to withstand higher temperatures, ensuring the system remains reliable even under demanding driving conditions.
- Brake Pedal Feel and Performance
- Problem: The Audi TT MK2’s brake pedal felt spongy and unresponsive, which is often a sign of air or moisture in the brake fluid.
- Solution: By replacing the brake fluid and purging any air from the brake lines, we restored the brake pedal’s firm and responsive feel, improving overall braking performance and driver confidence.
